ORCHARDTHEATER.

Specification of 'Letters Patent. I Patented Sept. 10, 1912.

Application led Hay 21, 19412. Serial No. 698,746.

ATo all whom t may concern Be itlmown thatliwe, NATHAN B. NEW- COMER andCARL 0. JOHNSON, of Paonia, in the county of Delta and State ofColorado, (each of whose post-office address is Pao- `nia,'Colorado,)have invented certain new .and useful Improvements in Orchard-Heaters;and wefdo hereby declare the following to be a full; clear, and exactdescription of the invention, such. as will enable others Skilled intheart to 'which it appertains to make and use the same. v The object ofour invention is to provide an improved "and etiicient heater for or!chards, in the use of which uniform radiation. of'he'at is secured inall directions without the creation of much if any smoke, and

with the consumption of but a minimum quantity of fuel. p

4In the drawings, Figure l is a View in perspective of our invention.Fig. 2 is ay vertical sectional view thereof. Fig. 3 is a modification.I

Referring to the drawings, l designates an open topcontainer orreservoir in which the fuel, preferably crude oil, is burned. Thiscontalner is shown as circular in crosssection, and is open only at thetop. lTwo ring-like platesf, 4, of slightly greater diameter than thecontainer, are designed to rest upon the upper edge thereof, and each isformed With a seriescf vertical openings 5, 5', respectively, theseopenings together forming a passageway through which air may be drawninto the container'. The plate 3 may be moved over the plate 4 for thepurpose of regulating the size of these openings and consequently theair inlet.

6 is a radiator whichwe haveshown in the form of an inverted frustumof acone.

Its smaller end fits within the centralv openmay be removed to increase'the draft, and may be employed as a cover for the container when thedevice is' not in use.

The crude oil is placed in the container and lighted, and the radiatorbeing in position, air is drawn into the container through the verticalopenings in the supporting ring and into the radiator through thehorizontal openings 7. In this way not only is a coniplete draftsecured, but substantially all combustible gases are completely consumedin the radiator, thus preventing smoke and securing thorough and uniformradiation of th'e heat.

Y In Fig. 3 we have shown a slight modification, the radiator 6 at itslower end being of approximately the same size as the top of thecontainer l upon which .it is designed to fit while itsV upper end is ofsomewhat 'smaller diameter. l-Near its opposite ends the radiator hastwo series of clicumfereir tial openings 7 and 8. f The admission of airthrough opening 7 l may be regulated by a damper l0, in the form of acircular band.

We claim as our invention:

l. In.combination with a container, a radiator mounted thereon, one ofsaid members having openings thereinto at their meeting ends, acircumferential damper for regulating the passage through saidopenings,l said radiator being closed at its top and havingcircumferential openmgs 1m-.

mediately adjacent said top.

2. Aportable orchard heater comprising an imperforate fuel container, aradiator', and ring-like lplates mounted on said container, and having'each a seriesv of-vertical openings', said radiator fitting on saidrings, and h ving auupper and lower series of air openiiilrs.

In testimony whereof, we have signed this specification inthe `presenceof two subscribing witnesses.
